ATI TEAS Science Questions
Question 1 of 5
Which of the following is the body cavity that contains the urinary bladder, urethra, and ureters?
Correct Answer: B
Rationale: The correct answer is B, the pelvic cavity. The pelvic cavity houses organs related to the urinary and reproductive systems. The urinary bladder, urethra, and ureters are located in the pelvic cavity, making it the correct choice. The thoracic cavity contains the heart and lungs, while the abdominal cavity houses organs like the stomach and intestines. The spinal cavity, on the other hand, protects the spinal cord. Therefore, options A, C, and D are incorrect as they do not house the specific organs mentioned in the question.
Question 2 of 5
Which type of chemical reaction produces a salt?
Correct Answer: B
Rationale: The correct answer is B, a neutralization reaction. In a neutralization reaction, an acid and a base react to produce a salt and water. This process involves the combination of H+ ions from the acid and OH- ions from the base to form water, while the remaining ions combine to form a salt. Therefore, a neutralization reaction is the specific type of chemical reaction that produces a salt. Choices A, C, and D are incorrect. An oxidation reaction involves the loss of electrons, a synthesis reaction involves the formation of a compound from simpler substances, and a decomposition reaction involves the breakdown of a compound into simpler substances. None of these reactions directly lead to the production of a salt, making them incorrect choices in this context.
Question 3 of 5
Which of the following best describes the function of synergists?
Correct Answer: D
Rationale: Synergists play multiple roles in muscle function. They assist primary movers in completing specific movements by working together with them. Additionally, synergists help stabilize the point of origin and provide extra pull near the insertion, contributing to the efficiency of movement. Furthermore, they also help prevent unwanted movement at a joint by ensuring that the intended motion is executed smoothly. Therefore, all the statements in the answer choices accurately describe the functions of synergists, making 'All of the above' the most comprehensive and precise description of their role.
Question 4 of 5
What is the final phase of mitosis?
Correct Answer: B
Rationale: Telophase is indeed the final phase of mitosis. During telophase, the chromosomes have reached opposite poles of the cell, the nuclear envelope is re-forming around the separated sister chromatids, and cytokinesis may also occur, leading to the division of the cell into two daughter cells. Choice A, Prophase, is incorrect as it is the initial phase of mitosis where chromatin condenses into chromosomes. Choice C, Anaphase, is incorrect as it is the phase where sister chromatids separate and move towards opposite poles. Choice D, Metaphase, is incorrect as it is the phase where chromosomes align at the cell's equator before separating.
Question 5 of 5
When testing how quickly a rat dies based on the amount of poison it eats, which of the following is the independent variable and which is the dependent variable?
Correct Answer: B
Rationale: The correct answer is B. In this experiment, the independent variable is the amount of poison because it is what is being manipulated by the researcher. The dependent variable is how quickly the rat dies, as it is the outcome that is being measured based on the different amounts of poison administered. Choice A is incorrect because the independent variable should be what is being manipulated or changed, which is the amount of poison in this case. Choice C is incorrect because whether the rat eats the poison is not being varied or controlled by the researcher. Choice D is incorrect because the cage the rat is kept in is not relevant to the relationship being studied between the amount of poison and the rat's survival time.
